Abstract: PROBLEM TO BE SOLVED: To solve a problem of a conventional power amplifier for high frequency that cannot cope with a requirement of miniaturization because a harmonic control circuit that is to be designed as a separate circuit is required be added to a power amplifier circuit being a component circuit of the power amplifier. SOLUTION: The high frequency power amplifier 11 consists of a high frequency amplifier section Q11, an input matching circuit 12 that is connected to an input electrode, an output matching circuit 13 that is connected to an output electrode, and a bias circuit that is connected to the output electrode and consists of distributed constant lines L14, L15 being division circuits of an originally one distributed constant circuit and of an inductor L16 connected in series between the distributed constant lines L14, L15, where a distance (d) between the distributed constant lines L14, L15 in a signal transmission direction is selected to be an open end correction length with respect to a 3rd harmonic of the high frequency signal.  Adopting the bias circuit for the high frequency power amplifier can adjust an output impedance of the high frequency power amplifier with respect to the 3rd harmonic without changing the output impedance of the high frequency power amplifier with respect to a second harmonic and enhance miniaturization furthermore.

Title: List output system for language processing system
Inventor: MIZUSE HARUMI
IPC: G06F9/45
Filed: 1990-11-14
Abstract: PURPOSE:To shorten a language processing time and to attain highly efficient debugging by forming a cross reference list by a list embedding type. CONSTITUTION:When the 1st symbol discriminating means 104 decides that a sentence read out by the 1st reading means is a sentence for defining a location address in a symbol, the same symbol name as the symbol is retrieved from a symbol name storing part 111 and the contents of a definition line storing part 112 which correspond to the symbol name are outputted to a symbol value storing part 113. Since the list type for directly outputting a cross reference list indicating the reference position of a symbol to a symbol defining position in a list source program is adopted, the symbol defining position and a symbol reference position in the program can be detected only by observing the list. Thereby, highly efficient debugging can be attained at the time of correcting the program or evaluating a real machine.

The depth of the unevenness of the designed surface of the cast molded board 1 is about 10mm. Next, under the condition that epoxy elastic adhesive 3 is uniformly applied to the rear surface of the cast molded board 1, a form steel plate 2 is pasted to the cast molded board so as to cure at room temperature. By mounting a frame and the like to the resultant mold, a concrete shaping mold base is formed. Then, concrete is placed in the shaping mold and cured. As a result, hardly warpage occurs in the concrete shaping mold.

Title: Semiconductor integrated circuit device
Inventor: HAMAMOTO TAKESHI
IPC: H01L27/10
Filed: 1989-11-27
Abstract: PURPOSE:To enable the amount of charge stored in a capacity element to be larger by using a first conductive layer of a part of the element also as a wiring. CONSTITUTION:A storage node 1 is one electrode of a stacked capacitor 15 and also performed as a role of a connecting wiring for connecting an impurity region 5b to a storage gate 14. Accordingly, a connecting wiring is not required, a contact hole for connecting the wiring to the region 5b is not required as well, and the lateral area of the region 5b is reduced that much. Since the area of a PN junction of a boundary between the region 5b and a semiconductor substrate 7 is also reduced, a leakage current from this part is reduced. Thus, charge to be stored in the storage node 1 is stably held.

IPC: G06T11/20
Filed: 1990-11-14
Abstract: PURPOSE:To omit processing for converting input data into a Bezier curve and to attain rapid display by converting a curve defined by a parameter expression into the data of an expression type whose display processing is easy, storing the converted data, and at the time of repeatedly displaying curves, displaying the curves based on the data of the expression type of easy processing. CONSTITUTION:A curve defined by the parameter expression is transformed into a Bezier curve by a polynomial expansion means 1a and a Bezier transfor mation means 1b and the transformed result is stored in a Bezier storing means 1c. A Bezier control point coordinate transformation means 1d fetches a Bezier control point from the means 1c by using coordinate transformation matrix applied so as to execute required visual field transformation, executes coordinate transformation and sends the transformed result to a Bezier generating means 1e. The means 1e expands the Bezier curve into a segment string, which is displayed by an ordinary method. Since it becomes unnecessary to transform the same curve or curved surface to a Bezier curve when it is displayed repeatedly, rapid display can be attained.

Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To make the opened- and closed-state of a shutoff valve by means of one kind of control section even when the shutoff valve is manufactured for different specifications or by a different manufacture.

Title: Automatic gain controller
Inventor: MIZUTANI AKIYOSHI
IPC: G01S7/285
Filed: 1988-12-07
Abstract: PURPOSE:To accurately correct a gain by providing a gain set value selecting circuit, selecting a gain set value according to the pulse width and frequency of a pilot signal, and outputting it. CONSTITUTION:The pilot signal for AGC (automatic gain control) which is implanted during a gain correction period in synchronism with an AGC timing signal is converted into a video signal through a variable attenuator 1 and then converted into a logarithmic value by a logarithmic converting circuit 2. A subtracting circuit 3 subtracts the level set value, selected according to the sent pulse width and frequency, from the converted logarithmic value. The output of the circuit 3 is added by an adding circuit 6 to a last gain set value and the sum value is the attenuation quantity (gain correction quantity) of an attenuator 1. This controlled variable is held by a holding circuit 7 until a next AGC timing signal is inputted. Thus, the accurate gain correction is made.
